We all know someone who is naturally talented in the ways of the musical arts. Someone who can walk up to a piano and just start picking out the melody to a song. Other people, well about the best they can do is whistle. Some people (like my wife) can't even whistle (and yes, I've tried to teach her, and now I just tease her about it). But everyone should be able to slap some tum-tum! The Happiness Guys prove that with a little practice and a nice round of pink belly, you can create some pretty kickass (or slap-flab) music!
